PACKAGE-TIER.

Specification of Letters Patent.

Application filed January 15, 1913.

Patented Nov. 25, 1913.

Serial No. 742,242.

To all whom it may concern.

Be it known that I, GEORGE A. ROBERTS, a subject of the King of GreatBritain, residing at VVo-llaston, in the county of Norfolk and State ofMassachusetts, have invented new and useful Improvements I inPackage-Tiers, of which the following is a specification.

This invention relates to package tiers or analogous binders; and it hasfor its object the provision of a device of this character which willinclude a locking disk and a flexible binding element, the latter beingassociated with the former in such manner that it may be convenientlywrapped about the package and then finally connected with the disk so asto positively prevent said flexible binder from casual derangement ordisconnection from the disk.

Another object of the invention is to provide a device of this characterwhich wi ll facilitate arranging documents, letter-sheets,

sample cards or the like to be readily bound in package form and in suchmanner that the package can be quickly opened when desired.

Another object of the invention is to provide a terminal locking elementon the disk and means for maintaining a fixed position of said elementso as to insure its proper presentation to the free end of the bindingelement.

With these and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts, aswill be hereinafter described and claimed.

In tne accompanying drawings :Figure 1 is a perspective view of thebinder, showing the application of the same to a package; and Fig. 2 isa section on line 22 of Fig. 1. Y

The device comprises a disk 1 of concavoconvex configuration, themarginal edge of the disk being up-turned as at 2, so as to present alower curved smooth surface 3, which is adapted to lie in direct contactwith the package. The disk is disposed with its convex-surface uppermostand as illustrated said disk is provided with a depression 4: havingstraight side walls and a vertical stop shoulder 5. This depressionaccommodates the inner terminal 6 of a retaining element of spring 7 Thespring is provided with a portion 8- which is curved away from theadjacent convex-surface of the disk, so as to provide an outwardlyflared entrance passage 9. The inner end or terminal .6 lies in contactwith the shoulder 5 whereby a definite position of the spring ismaintained upon the disk. A rivet 10 is extended through the terminal 6of the spring and through the central portion of the disk and then upsetat 11 against the concave-surface of the disk. Said rivet is providedwith an enlargement 12 terminating at-its inner end in a shoulder 13which is engaged directly against the upper surface of the springterminal 6. The rivet terminates in a guard head 14:, as illustrated.

The clamping element 15 is preferably in the form of a single strand ofcord or like flexible material which is wrapped around the enlargedportion 12 of the rivet and confined between the head or button 14 andthe adjacent surface of the convex-surface of the disk. Said bindingelement may be of any suitable length whereby it may be wound one ormany times around the package to provide right angularly disposed leadsand to permit the free knotted terminal 16 to be associated with thelocking terminal of the spring 7 and securely confined against theconvex-surface of the disk. It is of course understood that during theoperation of winding the binder in opposite directions around thepackage, the portion 12 serves as a fulcrum post, around which thebinder may be wound and then extended in any desired direction aroundthe package.

The rivet, as described, positively holds the inner terminal 6 in therecess whereby the spring is eflectually held against rotary movementsupon the disk. In this manner the binder receiving end of the spring isheld in proper receiving proximity relatively of the windings of thebinder so as to effectually receive the free end of said binder.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted'to without departing from the principle orsacrificing any of the advantages of this invention, as claimed.

Having thus described my invention, what I claim is A package bindercomprising a concavoconvex disk having a central passage therein and aradial recess formed on the convexity of the disk and terminating at itsinner end around said central passage and terminating at its outer endonto the disk at a point within the marginal edge thereof, a sheet-metalspring curved to conform with the convex-surface of the disk and havinga portion seated in the recess and having its free end curved outwardlyaway from p the convex-surface at a point beyond the outer end of therecess, a rivet having a reduced portion extending through the inner endof the spring and through the central passage in the disk and tip-struckagainst the walls of the concave-surface of the disk and having an upperenlargement extending above the convex-surface of the disk centrally ofthe latter and terminating in a relatively broad head lying in spacedrelation with the convex-surface of the disk and having ashouldersea-ted directly against the spring whereby to confine the latter in therecess and thereby hold the spring against moving around the rivet and aflexible member having one of its terminals secured to said rivet at apoint above the convex-surface of the disk.

In testimony whereof I aflix my signature in presence of two witnesses.
